Karbon Nanotüp (KNT) İlave Edilmiş Poliakrilonitril (PAN) Nanoliflerin Elektroeğirme Yöntemi ile Üretilmesi ve Karakterizasyonu
Bu çalışmada elektroeğirme yöntemi ile karbon nanotüp (KNT) ilave edilmiş poliakrilonitril (PAN) nanolif üretimi rapor edilmiştir. Boncuksuz ve düzenli PAN/KNT elektroeğirme yöntemi ile elde edilmişnanofiberler elde etmek için beş farklı KNT konsantrasyonu (0.05, 0.1, 0.2, 0.5 ve %1 ağırlık) denenmişve nanolifleri karakterize etmek için Taramalı Elektron Mikroskobu (SEM), Raman ve X-Işını Difraksiyonu (XRD) analizleri kullanılmıştır. Sonuçlar, artan KNT konsantrasyonu ile PAN/KNT nanoliflerinin çapınınarttığını ve optimum bir konsantrasyondan sonra nanolifler üzerinde bazı düzensiz bölgeler ve boncuklanmaların oluştuğunu göstermiştir. Bununla birlikte, KNT'lerin eklenmesi, PAN nanoliflerinin grafitizasyonunu ve kristalliğini arttırmıştır. Boncuksuz ve kristalizasyon seviyesi yüksek PAN/KNT nanolifler için optimum KNT konsantrasyonu ağırlıkça %0.1 olarak bulunmuştur.
Carbon Nanotube (CNT) Embedded Polyacrylonitrile (PAN) Electrospun Nanofibers Production and Characterizations
Carbon nanotube (CNT) embedded polyacrylonitrile (PAN) nanofibers production by electrospinning method was reported in this study. Five different CNT concentrations (0.05, 0.1, 0.2, 0.5, and 1wt%) were tried to obtain beadless and regular PAN/CNT electrospun nanofibers. Scanning Electron Microscopy (SEM), Raman and X-Ray Diffaraction (XRD) analyses were utilized to characterize nanofibers. The results indicated that with increasing CNT concentration, the diameter of PAN/CNT nanofibers increased, and after an optimum concentration some disordered sites and beads were observed on the nanofibers. However, the addition of CNTs enhanced the graphitization and crystallinity of PAN nanofibers. The optimum CNT concentration for beadless and high crystalline PAN/CNT nanofibers was found as 0.1 wt
